Abstract
A voltmeter probe has a metal probe tip projecting from an elongated insulating handle. The handle has a longitudinal axis and a radially projecting finger guard with an inner diameter and an outer diameter. A barrier covers the terminal. The barrier has an aperture configured to provide access for the probe tip to be inserted through the barrier into contact with the terminal, including access for the finger guard to be inserted through the barrier. The aperture has dimensions of length and width, including no width that is not less than the outer diameter of the finger guard.

An apparatus for use with an electrical terminal and a voltmeter probe having a metal probe tip projecting from an elongated insulating handle, wherein the handle has a longitudinal axis and a radially projecting finger guard with an inner diameter and an outer diameter, the apparatus comprising:
- a barrier configured to cover the terminal and having an aperture configured to provide access for the probe tip to be inserted through the barrier into contact with the terminal, including access for the finger guard to be inserted through the barrier, wherein the aperture has dimensions of length and width, including no width that is not less than the outer diameter of the finger guard.
An apparatus for use with an electrical terminal and a voltmeter probe having a metal probe tip projecting from an elongated insulating handle, wherein the handle has a longitudinal axis and a radially projecting finger guard with an inner diameter and an outer diameter, the apparatus comprising:
- a barrier configured to contain the terminal and having an aperture configured to provide access for probe tip to be inserted through the barrier into contact with the terminal, including access for the finger guard to be inserted through the barrier, wherein the aperture has:
- a first elongated section having a length greater than the outer diameter of the finger guard;
- a second elongated section projecting orthogonally from the first elongated section and having a width greater than the inner diameter of the finger guard;
- and
- a third elongated section projecting from the first elongated section oppositely relative to the second elongated section and also having a width greater than the inner diameter of the finger guard.
An apparatus for use with an electrical terminal and a voltmeter probe having a metal probe tip projecting from an elongated insulating handle, wherein the handle has a longitudinal axis and a radially projecting finger guard with an axial width, an inner diameter, and an outer diameter, the apparatus comprising:
- a barrier configured to cover the terminal and having an aperture configured to provide access for probe tip to be inserted through the barrier into contact with the terminal, including access for the finger guard to be inserted through the barrier, wherein the aperture has:
- a first elongated section having a length greater than the outer diameter of the finger guard, and has a width greater than the axial width of the finger guard;
- a second elongated section projecting orthogonally from the first elongated section, the second elongated section having a width greater than the inner diameter of the finger guard, and having a length greater than a length of the voltmeter probe from the finger guard to a terminal end of the probe tip;
- and
- a third elongated section projecting from the first elongated section oppositely relative to the second elongated section, and also having a width greater than the inner diameter of the finger guard.
